AlbertCity; Iowa, a corporation of Iowa Appiieatien retrain 14, 1946', serial Newer 20 claims, (Cl'.-226- 12'5 The present invention relates to new and useful dispensing apparatus, for dispensing liquids and particularly more or less viscous liquids such as, for instance, lubricants (such as greases and viscous oils, printers ink, caulking compound etc), and which relates more particularly to dispensing viscous fluids from an orig-- inal and relatively thin-walled and inexpensive vendable merchandising container (namely, a container in which the fluid or semi-fluid is originally packed,- shipped, stored and sold) preferably by suction applied to an outlet-opening in the bottom of the container while the' top of the container vented to the atmosphere.

One of the objects of the present invention is to suction-dispense such viscous fluids, as, for instance, lubricants, from an" original Inefchandising container, vented'at its top, through an opening in the bottom thereof (either with or without the need of removing the lid or top of the container) as for instance, for dispensing such more or less viscous fluids or semi-fluids through an opening in the'bottom of a sheetmetal container such as a 1b., 25 lb. 01"40 lb. (more or less) capacity pail, can or the like, preferably with bail-like carrying handle, by mounting such sheet-metal container on a dispausing-base or gun-loading pail-"base or transfer-base which has a conduit or fluid passageway therethrough, with one terminal of the conduit generally in the center of the top of the base, and with the other terminal of the said passageway in or on the sidewall of the base, and with the upper conduit-terminal arranged sealingly to engage the relatively small opening in the bottom of the pail or original container and with the side-terminal of said conduit communicating with a socket-"like coupler for making detachable connection with the barrel or reservoir of a grease-.gun or' the like suction-producing device or for connection with any other lubricant-dispensing pump or the like and means intermediate the dispensingbase and the sheet-metal container for making temporary interlocking engagement between the two, and for firmly securing the container to the base.

Other objects of the present invention will appear from the following descriptionand the accompanying drawings, wherein I have shown, for the purpose of illustrating my invention, forms thereof which are at present preferred, although it is to be understood that the various instrumentalities of which the invention consists can be variously arranged-organized and that the invention is not limited to the precise arrangements and organizations of the instrumentalities as herein shown and described.

In one embodiment of the present invention, the thin-walled original vendable merchandising sheet-metal container, pail or can designated generally by the letter C and shown in Figures 1, 2, 5, 8 and 10, is preferably formed with a cylindrical side-wall I having its uppermost portion 2 flared outwardly slightly with a beaded edge96 and having a lid or cover 3 secured to the upper end thereof either by means of the crimped tags 4 or by any suitable means.

The sheet-metal bottom 6 of the container C is initially imperforate and is provided with a downwardly depending more or less cylindrical flange-like portion 1', which telescopes into the lower end of the cylindrical body 1 of the container C, to a greater or lesser extent, depending upon the axial length oi flange i, and is secured thereto by an interlocking crimp'ed seam 3.

The sheet-metal bottom 6 may have pressed into it, in a downward direction (or-in an upward direction) an annular groove 9, to :form a doughnut-like ridge or annulus on the outside (or on the inside) of the bottom '6'; "the outer (or --inner) more or less flat or rounded annulus-like surface it of which constitutes a seating=suriace for making sealing con-tact with an annular sealin'ggasket oi ring H (of cork, igrea'se-xresi'stant rubber or composition or other suitable -resilien't material) carried by the base B," see Figure 3. The annulus 9 is preferably centered, or approxima'tely centered, in relation to the periphery of the bottom 6.

The annulus 9 also serves to stiffen the center of the bottom 6, so that the circular disc-dike portion i2, within the center of the annulus can be more readily cut out or knock'ed 'o'utiby the cutting action of the cutters (as in the embodii ment herein shown and described) or by any other suitable disc-removal operation. The annulus 9 centers or guides the cutters or knives l3, during the cutting operation, and serves also to stifien and reinforce the center of the bottom 6 after the disc I2 has been out out or removed therefrom.

The container may be of relatively thin sheetsteel or plate, as, for instance, 26 gauge sheetsteel or plate (approximately ..0l8 inchthickness) for a 25 lb. .pail or 30 gauge for :a '10 lb. container or 24 gauge for a 50 lb. container.

In one embodiment of my invention,aplurality (2, 3 or 4, more or less) of circumferentially distributed equidistant bayonet-lugs [4 may be pressed outwardly (or inwardly) from the sidewall i of the container C, for interlocking connection with the base B.

Within the container 0, near its upper end thereof, is a follower 5, which (in one embodiment) is held to the lid 3, while the container C is filled and while the container C in transit and in storage, prior to its actual "use, by means of the screw 93 orthe like, in the manner hereinafter described, and which is released from the lid 3 when the container is .put into use on the base B.

In one embodiment of the base..phase1 f'my present invention, illustrated in the drawings, the base 13 may be formedof three-members 15, I6 and H (see Figure 10)., which may be welded to eachother or may be interlockedby seams l8 and it, so as to form a generally unitary :construction, in which each member supports and .gives rigidity to the other, therebypermitting the three members to be formed (by pressing between dies or by spinning or by rolling, orthe like) out of relatively thin sheet-steel as, for instance, or 22 gauge sheet-steel for a base for a lb.:container, or other relatively thin sheet-metal and yet maintaining adequate strength and rigidity in the finished base B.

and is being arranged with their transversemortions or bottoms -i-n juxtaposition and in generally contiguous relation to e'ach other, that --is,

with the bottom :20 of the upper member I5 extending downwardly and with the bottom 2| of the lower memberl 6 extending upwardly, thereby reinforcing each other to give the desired rigidity to the composite of two-ply partition-wall designated generally by the numeral 22.

The cylindrical portions .23 and 24, respectively, of the members 5 and I 6, may be either the same diameter or of different diameters, or either or both of them may he stepped inseveral diameters or tapered, in'the form of a truncated cone. in the embodiment of the invention herein shown, the upper flange 23 .is cylindrical, while the upper diameter of the lower flange 24 :is substantially thesame as that of the flange .23, and the lower flange tapers outwardly in the form of atrunsated cone.

The outer hoop-like member 11 may be made by curving 'a strip of flatsheet-metal intora hooplike circle and welding or otherwise securing the ends of the strip to each other, and may be made approximately to fit the diameter or diameters or steps or taper of the peripheral or flangelike portions 23 and 24 of :members 15 and I6, or it may be spaced away therefrom in an outwardly direction, throughout (or over part of.) its extent. In the forms-showm'the member I? is :in generally contiguous relation to the :sides or flange-like portions 23 and 224 of the members It or 16.

In the end-wall oribottom 2s, a center aperture 25 is formed, and thematerialfrom'theaperture 25 may be pressed -or drawn upwardly to form a short upstanding tube-like cutter-supporting intake-flange or intake member 26, although this tube-like cutter-supporting intake- .flange or intake member is preferably formed separately, as shown in the drawings, and spotwelded or crimp-'seamedto the aperture 25. The metal around the hole r25 may be pressed down in a downwardly extending annulus 21,, forming an annular groove around the tube-like flange 26, for the reception and retention of the resilient and grease-resistant packing-gasket or sealingring ll.

cludes the projected area :of thehole25 (and may also include the projected area of the .annulus 27 which channel 28=extendsiaterally outwardly to the side-wall 24 of the member .15, .so .as to .form a fluid-conducting passageway :or conduit 1 extending from the hole 429 (Figure .8) which is ultimately formed in the bottom-of the original container, pail or can 0, outwardly t the greaseegun-rec'eiving socket 3t .formed in or aiiixed to the side of themember ill.

From the more or less cylindrical member ii, a circular flange 3! (Figure 10) is drawn or pressed outwardly, in general alignment with the outer end of the passage-way .or conduit 28, and preferably turned/upwardly at a'slight angle, so that the plane of its outer edgewill be inclined upwardly slightly-from the vertical. The circu lar center portion of the flange 3| is-cut-out, and the generally tubular flange 3| is thereafter; crimped or flared outwardly "as at .33, to overlap and interlock with theiinturned flange '34 of the gun-receiving socket 30; the crimped portion 33 of the tubular-drawn flange 31 :serving also as a seat-for the sealing :gasket 35 (Figure 11) against which the end :36foi the barrel 'or v'reservoirlal of the g-reaseegun is adapted sealing- -ly to bearpwhen its screw-threaded end 38 is screwed into the internally screw-threaded portion of the gun-receiving socket 30.

The inner surface 39 surrounding the tubular flange 3! may serve as a valve-seat against which a round shut-off valve 40 is adapted to seat in a direction of the ,arrow 4|, and from which it is unseated in the direction of the arrow 42. The shut-off valve 40 may be carried by a valve-stem or rod 43 which may be guided by a pair of journal brackets 44 and 45 fastened (by spot welding or otherwise) to the wall 20, and the valve is urged into a seating position by helical compression spring 45 which bears against a cross-pin, disc or other abutment 46-a aifixed to the stem 43. The other end of the valve-stem 43 carries an operating extension 41, which extends outwardly to a suitable distance, so that it may be contactingly engaged by the multispoked button 48 which is fixedly carried in the front end of the grease-gun barrel or pump-cylinder 31. The button 48 may be held by the spokes 49 which may be held in place by being spread out into an annular groove 50 formed in the inner surface of the outer end of the gun-barrel 31, or may be otherwise secured in the barrel 31, as, for instance, by butt-welding the ends of the spokes 49 as, for instance, by electrical-resistance heat or resistance-welding to the inner sidewall of the barrel 31 by unbending the bowed portions of the spokes 49 to spread the ends thereof into firm contact with the cylinder 31 while welding-current is connected across the spokes and barrel, or by spot-welding the ends of the spokes which have been previously bent parallel to the side-wall of the barrel 31.

Thus, when the gun barrel or pump 31 is screwed into the socket 30, the center portion of button 48 presses the valve-extension 41 inwardly so as to unseat the valve 40 and to permit the lubricant to be drawn out by the manual retraction of the piston within the barrel or cylinder 31, by the manually operable retracting rod or piston rod 52, or by the suction of any other pump-piston.

Instead of the inwardly and mechanically unseating valve 40, I may provide a suction-unseating valve 53, various arrangements of which are shown in Figures 26, 2'1 and 28, opening outwardly or generally in the direction of the fluid-flow, which may be similarly affixed to and carried by a similar valve-rod 43 and journal or bearing brackets 44 and 45, and seated by a spring 45, but this time against the outer turned periphery 54 of the tubular flange 3|, as in Figure 28 or against the inner periphery of the hole 25, as in Figure 26, or against the inner periphery of a valve-hole 55 in the valve-seat wall 56 interposed in the conduit 28, as in Figure 2'1. Either valve, namely, the inwardly and mechanically unseated'valve 45, or the outwardly suction-unseated valve 53, may be placed within the channel 28 Or at the opening 25.

Instead of a rod-carried valve (40 or 53), with rectilinear unseating motion, I may use a flapper-type hinged or pivoted-valve, pivoted at its top, for gravity-seating, or pivoted either at its top or bottom, or at its sides, and seated by any suitable valve-closing spring.

Into the cylindrical side 23 of the upper dishlike base-member l5, and, if desired, also into the co-extensive cylindrical zone of the hooplike outer member l1, a plurality (two, three or four) of circumferentially distributed and equidistant similar. bayonet-grooves or channels 51 are pressed (or otherwise formed) in an outward direction (as in Figures 1, 3, 8, 10, 19 and 23) or in an inward direction (as in Figures 22 and 24) with their outer ends 58 passing through the upper edge 59 of the base member B and with their lower inner ends til blind. See Figure 30.

Each of the bayonet-grooves or channels preferably has a more or less vertical entrance portion 6! of a length such that the traverse of the bayonet-lugs I4 downwardly therethrough is suflicient to cause the cutters l3 fully to pierce and fully to extend through the bottom of the container C; the upper edge 59 being so spaced in relation to the ends of the cutters l3 that the extreme ends of the cutters will not quite contact or at least will not pierce the sheet-metal of the bottom of the container C while the lower surfaces of the bayonet-lugs 14 are riding on the upper edge 59 of the base B, or are at the plane or the edge 59, and so that the bayonet-lugs 14 must enter the more or less upright portions [ii of the bayonet-channels 51 before the cutters i3 can efiectively engage or pierce the bottom of the container 0.

The bayonet-channels 51 have more or less horizontal portions 62, through which the bayonet-lugs l4 pass by rotating the container, after the cutters it have been pushed through the bottom of the container, so as to cause the pushed-through cutters circularly to cut through the bottom, or to make a complete circular cut, and thus to make a complete circular hole 29.

The length or the more or less horizontal cutting portions 62 of the bayonet-channels 51 depends upon the number of cutters and their arcuate extent. Thus, the amount of turning of the can required for a full cut-out, is that fraction of a turn which will cause the leading edge of one cutter arcuately to travel through the metal (of the bottom) until it meets the initiallypierced hole left behind by the cutter ahead or" it. The greater the number of cutters in the circle, or the greater the arcuate width of the base of the cutters, the less turning is required, and, hence, the shorter the portions 62 of the bayonet channels 51. Preferably, the length of the portions 52 of the bayonet-channels 51 is slightly greater than the minimum turning required, so as to give a slight margin of clearance and thus to insure a full circular cut-out.

The bayonet-channels 51 then dip downwardly at a suitable angle as at 63 (see Figures 30 and 34) so as to pull the can downwardly after the hole 29 has been fully cut in its bottom, and thereby sealingly to seat the reinforced and stiffened annular sealing-surface l0 (surrounding the cut hole 29) against the sealing gasket II and so as also to seat (or nearly seat) the seamed and headed bottom edge 64 against the more or less horizontal transverse surface 23 of the upper dish-like base-member 15. The annular portion 65 of the bottom of the can or container C (Figure 5) is resilient so as to permit the doughnut-like reinforcing portion '9 (of the bottom 6) and the sealing-annulus [B thereof, to be displaced to an appreciable extent or more or less), in a generally axial direction. The upper and lower ends of the inclined portion 63 of the bayonet-channels 51 are so positioned, vertically, in relation to the outer portion of the wall 25 of the base-member l5 which contacts '(or is. in vertical alignment with) the lower beaded edge 64 of the can, that the relative vertical disposition or spacing of the seating- ,s'urfaceilu and of the upper surface of the more assets? or les re l ent sealin asket .I in relati n to the upper and low r ends of the inclined-po tions .3 o he b yon t-channe s 51, s such hat e annula s t e urface I is rou ht int contact with the upper surface of sealing-gasket II before the bayonet-lugs [4 have travelled down the entire length of'the inclined portions 53, so that the continued downward inclination of portions 63 causes the annular portion 65 of the bottom 6 of the can C to be forced upwardly so as to exert a resilient spring-like force which will maintain effective contact-pressure between the annular seating-surface I0 and the sealinggasket I I when the bayonet-lugs I 4 have travelled all the way down the inclines 53 and have reeded slightly (in an upward di ction) in o the slightly upturned terminal portions 60 of the bayonet-channels .51; this slight reverse-turn serving as an over-lock, while the upward force ex r ed upon th Wh e an by th upwa dly ed d t n oned botto of the c n) tends to keep the bayonet-lugs I4 in the slightly upturned terminal portions 60 so as to prevent accidental unlatching or unlocking of the can Q from the base B. The sealingrgasket I I is also preferably resilient, so as to provide a further take-up of any slack or clearance which might otherwise exist in the locked position of the can C and base B.

The basal portions of the can C (namely the rti al d sp t on. of the ati -surface lo th e f a d h l wer dge 64 thereof and the bayonet-lugs I4 thereof) may be so arranged, proportioned or disposed in relation to each other and in relation to the corresponding partition of the base, that the lower edge 64 of the skirt of the can will seat or bottom against the juxtaposed outer peripheral portion of the partition wall 20 of the upper base-:member l5, when the can is in its finally locked position on the base, or these elements may be so disposed or proportioned in relation to each other, that the lower edge 64 of the skirt of the can will not quite seat or bottom on the base (as indicated in Figure 1), but so that the can will be bottomed on the base only on the sealing surface I0 thereof, and so that the can will be held fully tensioned between the sealing-surface It thereof and the bayonet-lugs I4 thereof (as indicated in Figure 23); the base pushing upwardly on the sealing-surface I0 of the can and pulling downwardly on the bayonet-lugs I4 of the can, with the resiliency of the annular portion 65 of the bottom 5 of the can serving asthe tension means to keep the bayonet-lugs pulled upwardly into the upper-turned terminal portions 60 of the bayonet-channels 51 of the base.

'I may also so arrange the basal portions of the can C (namely, the high of the bayonetlugs I 4 relative to the lower edge 64 of the can) and the can-receiving portions of the base B (namely, the height of the lowermost, portions I54 of the bayonet-grooves or channels 57 in relation to the outermost annular portion I 05 of the upper dish-like member I5 of the base B) and the relative height of the sealing-seat I0 in relation to the gasket II, that the sealing-seat I0; Will be firmly seated against the gasket II under the influence of the tension created in the annular portion, (55 of the bottom of the can, when it is dished upwardly by the sealing pressure between l5 and I I, and yet so as to permit the l wermosted e, 64 of the can to sea against the, annular portion I05 of the base when the bayonet-lugs I i have receded slightly into the its ing the bayonet-lugs I4 formed as gradually curved members, instead of defining a sharp or distinct horizontal surface, and by having the portions 52, 63, I04 and 60 of the bayonet-channels 51 also gradually curved in vertical crosssection, so that when the lowermost edge 54 of the can has seated firmly against the annular surface I05 of the base fB, just before the bayonet-lugs I 4 glide past the lowermost points I04 of the bayonet-channels 51, the can may, nevertheless, be turned further so as to bring the bayonetlugs I4 past the lowermost points I04 of the bayonet-channels 51, into the up-turned portions 60 of this bayonet-channel, by causing the bayonetlugs and the bayonet-channels to give slightly in relation to each other, either by the slight inward resiliency of the side ofthe can at the points of the bayonet-lugs, or by the slight resiliency oi the bayonet-lugs themselves and their ability partly to ride up on the sides of the bayonet-channels as though'they were to ride out of the channels, until the bayonet-lugs have passed the lowermost points I04 of the bayonetchannels 57. In this manner, I- may firmly seat the lowermost edge 64 of the can against the annular portion I05 of the base, while at the same time, the bayonetelugs have receded into the slightly up-turned portions 60 of the bayonetchannels 5?; simultaneously maintaining the seal between I0 and I I under the influence of the pressure of the up-dished and tensioned annularportien 55 of the can-bottom.

This ccmbinationcof the outer peripheral seating of the can-ed e 54 against the, base (as at H35, Figure 10, see also Figure 19'), and the tension-sealing of the center-hole 29 of. the can against the gasket II on the base, may also be accomplished (or augmented) by providing a continuous or an interrupted resilient peripheral annular seat in the portion I5 of the base, so that the lower edge 64 of the can will be firmly seated against the base even after the bayonetlugs I4 thereof have receded upwardly into the slightly up-turned portions 50 of the bayonetchannels 51, without necessarily relying upon any give between the bayonet-lugs and the bayonetchannels while the former pass the lowermost points I04 of the latter; at the same time maintaining the seal between the .seat I0 and the gasket II under the influence of the downward force of the annular portion 65 of the bottom of the can caused by the tensioning of said portion 65 when it is up dished by contact between the seat I B and gasket I I.

Such annular resilient seat at I05 in the outer periphery of L llie dish-like portion I5 of the base B maybe provided by a plurality of circumferentially distributed upestruclr bowed leaf -springs (not shown) pressed out of the sheetmetal 20 of the member I5, along its periphery I05, with one end of each such bowed leaf-spring being left integral with the original sheet, and the other end being free to ride and to be supported by the registering portion it of the sheet-metal of the lower wall 2| of the basemember I6; such up-bowed leaf-springs being distributed around the periphery more or less equidistantly, and being disposed more or less parallel (or tangent) to the periphery I05 of the base.

I may also form a plurality of generally radially disposed up-struck leaf-springs from the wall 20, with their inner ends left integral with the wall 26 and with their outer ends free of the wall 20 and bowed upwardly a slight extent so as to form resilient fingers extending a sixteenth or an eighth of an inch above the surface [05, so as resiliently to engage the can-edge 64.

Instead of drawing the cutter-supporting intake portion 26 out of the metal of the bottom 2B of the upper base-member I5, I may form the cutter-supporting intake member 26 separately, by drawing the same out of a separate piece of sheet metal, as shown particularly in Figures 8 and 9, and then spot-welding or otherwise securing the base flange 61 thereof to the downwardly extending annulus 2? formed around the hole 25 in the wall 20 of the upper base-member l5, as shown, for instance, in Figures 8, 10, 19, 22 and 26 to 29.

The cutter-supporting member 25 has parts of its cylindrical portion cut away to provide large side-openings $8, with vertical leg-like portions 69 intervening, to support the upper inturned flange H3 (see Figures 12, 13 and 17) upon which rests the flat cutter-annulus H with its upturned cutters 13. In Figure 15 this cutterannulus, with its cutters, is shown in a flat condition, as pressed out of suitable sheet-steel (capable of being tempered to hold a cutting edge), and before the cutters i1! thereof are bent upwardly, hardened and tempered. The cutting edges '12 of the cutters l3'are beveled to a sharp cutting edge, on the inside, so that the sharp cutting edge is preferably at the outer surfaces of the up-turned cutters I3.

A plurality of notches 13 mayb provided in the cutter-annulus H, for the reception of the crimping and locking lugs 14 carried at the inner periphery of the in-turned flange 10 of the cutter-supporting member 26 (see Figures 9 and 12 to 17). The cutter-annulus H is secured to the flang 10 of the member 26 by bending the lugs 14 upwardly and outwardly into the notches or recesses 13 of the annulus H, and then pressing the so out-turned lugs 1'4 tightly against the cutter-annulus, as, for instance, shown in Figure 9. If desired, a disc-ejecting spring 15 (as shown in Figures 8, 10 and 16 to 18) may also be secured in the central opening of the cutter-annulus H,

for the purpose of ejecting the discs [2 (see Figure 1) which have been cut out of the bottom of the cans, so as to prevent these discs from piling up on the top of the central opening I06a'in the cutter-annulus H and in the cutter-support 26. The spring 15 is preferably of a spiral form, so that it can be pressed flat into the plane of its outermost and bottom coil It. This outermost or bottom coil or turn 16 may be fastened beneath the lugs 14, as shown particularly in Figures 16 and 17. Thus, when the can is pressed down over the cutters, the spring 15 is collapsed flat so that it will not interfere with the cutting operation, and when the disc I2 has been fully cut out, then the spring forces the disc upwardly into the body of grease, and away from the central hole I06 in the cutter-annulus H.

The horizontal dimension (as well as the vertical and diagonal dimensions) of the lateral intake openings 58 are suificiently less than the diameter of the cut-out disc 12, so that the cutout disc I2 may not enter any of the openings 68 either in vertical position or in horizontal position or in a position diagonally of the holes 68.

The base B may be united by interlockingly crimping or rolling together the lower edge of the 12 base-member lii and the lower edge of the outer hoop-like member IT, to form either an outwardly extending rolled bead-like seam 19, as in Figures 1, 3, 8, 10, 11, 19, 22 and 26 to 29, or by rolling them inwardly to form a similar inner bead 78,

as in Figure 4. The outer hoop-like member El may be united with the upper base-member 45, by similarly rolling the upper edges thereof into a bead-like seam l8, which may extend outwardly as in Figures 1, 3, 4, 8, 10, 19 and 23, or may extend inwardly as at in Figures 22 and 24. Likewise, the beads, as, for instance, the upper beads l8 and 80, instead of being hollow round beads, as indicated particularly in Figures 8, 10,

19, 22, 23 and 24, may, instead, be flat, tightcrimped seams, similar to the seam 19 illustrated in Figure 4.

Likewise, instead of the inter-folded or intercrimped lock-seams 18, I9, 19 and 80, the upper and lower base-members l5 and 16 may be united with the outer hoop-like base-member ll by welding a continuous line through the two sheets, near their edges, throughout the perimeter, so as to form a fluid-tight seal.

Instead of (or alternative to) the continuous line-weld to unite the dish-like member It to the outer hoop-like member 11, or to unite the upper dish-like member Hi to the hoop-like member 57, I may use a series of circumferentially distributed spot-welds at suitable intervals, to unite the con tiguous skirt-like portions of IS and I! to each other, or to unite the skirt-like portions of i5 and H to each other. Because the transverse walls 20 and 21 of the dish-like members I5 and 16 may be firmly pressed against each other, at the same time that such spot-welding is accomplished, such spot-welding may, alone, provide sufiiciently fluid-tight seal between the transverse walls20 and 2|, to retain the more or less viscous fluid in the channel 28 without leakage, and without dissipating the suction created by the pull of the piston 5| of the barrel of the grease gun (or the like). I

The lower edges of the base-member IS with the outer hoop-like member I! may be flared outwardly to a radial extent greater than that of the bead 19, so as to form an outer floor-flang of a half inch or so (more or less), and such flanges may then be seamed together by an inter-folded or inter-crimped lock-seam or by welding or otherwise. Such outwardly extending flange will provide a greater floor-contact area for the base and will also permit the feet of the operator to rest on the flange so as to hold the base down on the floor during the application of the can to the base, particularly during the turning required for the cutting operation and the bayonet-locking operation.

The more or less vertical portions 6| of the bayonet-channels 51 may be pressed into the beaded portions I8, 19 and 80 of the upper edge of the base, or they may be similarly pressed into the welded upper edges, where an upper weld-line is used to unite the upper edges of the flange 23 and the member 11 (in place of the beads 58, 79 or 80).

In the embodiments of the invention illustrated in Figures 1, 3, 8, 10, 11, 19 and 23, the upper cylindrical portion of the base (formed of the flange 23and the upper part of the member 17) telescopically surrounds the lower part of the can 0, while, in the embodiment illustrated in Figures 22 and 24, the bottom of the can telescopes down over (and on the outside of) the top oi the base. In the embodiments illustrated in assets:

Fi ur s 2, 3, 8 1,1, 19. and 23, the inter-fielded or inter-crimped lock seam .8 at. the bottom of the can C. is preferably rolled inwardly, so that the outermost diameter of such seam 8 will not extend substantially beyond the outer diameter of the can-body, so as to permit the. side-wall of the can to be fitted more closely to the inner diameter of the cylindrical wall 23 of the upper base-meme ber I5, and thereby to permit the use of a bayonet-lug M of smaller radial extension.

In the embodiment. illustrated in Figures 22 and 24, the seam 8 is disposed entirely on the. outside of the main can-diameter, so. as to leave the inner diameter of the base-projection of the can flush so that it may telescope over and on the outside of the upper part of the base, with closer fit, and thereby to permit the use of the inwardly extended bayonet-projections. L4 of minimal radial extent.

While the bayonet-lugs I 4 may be pressed or drawn 1' m the 2-ply skirt-like portion i? of the can (as in Figure 5), bya die-pressing operation, they may also be formed of a separate stamping, or the like, as, in Figures 31 to 33, i clusive, and 35 to 3'7, inclusive, wherein a separate sheet-metal stamping is formed with a bayonet,- l-ug M pressed therefrom, with the flange 83 of the stamping spot-welded to the side of the can, By this means a bayonet-lug of greater radial extension may be Provided, In either event, how v r, the bayon proj c i n 54 i p f b ly placed at ornear he level of the transv r bottom 6 of the can 0, so that the bottom of the can will serve as a radial stiffener to prevent th l aps n of t e sid of t e an by the red ai pr ssur n ident to th a ne o in of th can to the base, 7

In Fi u s 5 37 l Q ll i d mD 3" -1 elongated bayonet-lug is illustrated, This clone t d lu may e used wh re it. is des re t obtain a broader contact surface between lug and bayonet-channel, particularly in the final or iocked position of the can and base, where the bayonet-lug rests in the slight upturn d terminal portion E5! of the bayonet-channel. this embodiment, the bayonet channels are made wider in their down-portions, as, for instance,

in the portions Bi and 53 thereof, to accommcdate the reater circumferential extent of the bayonet-lug, as shown particularly in Figure 34. Such elongated bayonet-lug (as distinguished from the round bayonet-lug) may be either formed separately as in Figures and 3'7, inclusive, or may be formed integral with 'the side of the can by being pressed or drawn from the 2-ply skirt portion 11 thereof.

Where the separate bayonetelugs are used, that is bayon -lu me b rs form d separately and then welded or otherwise secured to the id of th ca t e bayone loss are e e a ly at a level o t at the me or the dense 33 thereof will straddle the line of the bottom 5 of the container.

In Figures 22 and 25 a dual or 2-way acting valve is shown for the gun-receiving Socket e8, h re n the inwar ly ope in val e disc died rr p ndin to th al e d s it, the ex: mr flcat n her ore de cri ed) is. h r forated as at 85, and provided with a central aperture 86, through which the valve-stem 23 may freely and slidably pass. The valve-stem 43, in this embodiment, is preferably of a di ameter s ightly less han th di meter of the val e itens on t and as ond valveed e 5.3% corresp nding gen rally to he va ve 513 he em odimen s: he etciore de cribed, is in erposed. between the valve ten ion 41 and the e: tem the diame er of: he isc 53=c being suificient to cover the apert -es 85 in the valvedisc sail-c. The out'waroily closing valve-spring (corresponding to the valve-spring ts in the embodiments heretofore described) is here interposed between, thevalv-e-disc 4 an the ghi bracket 45, while a second Spring 8'! is interposed between the other side of the guidebracket 4,5 and the emarged inner end 88 of the valve-stein 43-, so as to pull the valveedisc, 53-.-o against the valve-disc 40-a.

By this means the passageway 33 may be unvalved either by the suction created by the piston 5i, or by the action of the button 48, when the barrel of the grease-gun is screwed into the socket 39,. Thus, in this form of construction (illustrated in Figures 22 and 25) and the dispensin apparatus of the present invention may be operated either by a grease-gun having a valveeopeningor valve-depressingmember, like or similar to the member 48 (Figures 10 and 11) or it may be operated by a. rease-gun barrel without such member (as, for instance illus-.

trated in Figure 22'). V

In place of any valve, one or more, bafiles 89 may be placed in the conduit 28 (as illustrated in Figure 29)., preferably in staggered relation to each other, so as to give some resistance to the iiow of grease thereby to prevent the free spilling of the grease, when the greaseegun bare rel 3! is unscrewed from the socket 30, and be-. fore the socket can be, closed off by a screw: plugor other closure means.

likewise a flow-limiting orifice-plate (not shown) may be placed in the conduit 28, to prevent free flow and yet permit suctioneinduced or pressure-induced flow.

The container (3" may be provided with a follower plate 5 (Figure 5) having an upper domes-like extension 90, pressed upwardly therefrom or formed separately and aflixed thereto, to clear the cutters I3 when the follower is in its bottom-most position upon the complete exhaustion of the grease or other contents from the container. The follower 5 preferably also has its main annular portion 9| flared slightly or dished upwardly slightly, towards the center, to conform generally with the upward dishing of the corresponding annular portion of the bottom '5 of the container, when secured in place on the base B. The dome-like member 9% is completely closed, at its top, and may have a slightly downwardly-dished central portion 52, to ive clearance for the end of the screw 93. A perforated disc or band 94 is extended across the downwardly-dished portion 92 of the dome 90, and into the central aperture of the mem-. ber 9.4., the screw 9.3 is screw-.threadedly secured so as to permanently hold he f llower 5 in its upp rmost position, with the upper d e o it cylindrical. flan 95$ firm y a nst the upp r surface oi thelid 3.- The'lid 3., in this em d ment of the invention, need not be pried loose from the beaded upper edg 8 0i t e can. bu ma be l ft hereon, intac while the r ase s. being exh usted theref om thr ugh. h b Ii-T Eh s. aft r the. can.

the same to the can to the base) the screw 93 is unscrewed and removed from the central aperture in the dome-like portion 81 of the lid or cover 3 of the can, thereby creating a vent hole in the topof the lid, so as to permit air freely to enter the container, above the follower. Thereafter, by applying the barrel of the grease-gun to the socket 39, and pulling the piston 5| of the barrel backward, the grease is sucked out of the container through the intake member 26 of the base, through the radial passageway 28 and out through the socket 30, thereby filling the grease-gun barrel.

In place of the tab type lid 3, a permanently lock-seamed upper can-end may be provided, so that the can cannot be refilled because the lid cannot be pried loose and replaced.

I may also provide a separate follower 5-a, not included in the can, when the can is filled and closed, and a separate lid 98 having'a handle 99 and a flange Hill of suitable thickness, through which two or more wing-screws It! may be ex tended radially to engage beneath the bead-like upper edge 85 of the can C. In this embodi merit, illustrated particularly in Figures 19, and 21, the original cover 3a of the container may be without any central dome-like portion Q? and without any central venting aperture or screw, and is pried loose and removed (as in Fig ure 21) before the container is put to final use, and is replaced by the cover 98, after the follower 5-a has been inserted into the container on the top of the grease. By this construction, a less expensive container may be provided, because the follower 5 need not be duplicated in each container.

As stated above, the dome 90 of the follower 5 or of the follower 5a, may either be made integral with the follower, as indicated in Figure 19 or it may be made as a separate piece, stamped out of sheet-metal (or otherwiseformed) as indicated in Figures 5, 6, 7 and 8, with its flange iii'l either spot-welded or line-welded to the overlapped portion of the annular part SI of the follower, immediately adjacent the center-hole therein, as indicated in Figure 8, or it may be united thereto by a crimped seam as indicated in Figures 5, 6 and '7, wherein either an inturned flange I08 or an outwardly turned flange 09, formed on the dome-element 90, is crimped to and interlocked with the edge of the hole of the follower-annulus 9|, as in Figures 5 and '7, or in which the flange I0! is embraced by a crimpedseam formed of a flange H0 drawn from the sheet of the follower, along the center-hole there of, as in Figure 6.

While in the drawingsI have shown the bayonet-projections formed on the side of the can or pail, with the bayonet-channels or grooves formed in the base, I may also, as an alternative embodiment of the present invention, form the bayonet-channels or grooves in the 2-ply skirted bottom portion of the container or pail, and form the corresponding bayonet-projections on the base.

In either form of construction, the tensioning of the bottom of the container or pail, when the opening has been formed therein and when the container or pail has been securedto the base, serves to prevent or retard the unlatching or the disengagement of the container and base, in respect to each other.

The present invention may be embodied in other specific forms without departing frdm the spirit or essential attributesthereof, and it is therefore desired that the present embodiments be considered in all respects as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent is:
